Aachen Researchers Revolutionize Lithium Foil Production with 'LIMA' Method
Aachen-based researchers have developed a revolutionary method, 'LIMA', for producing lithium batteries. This process promises significant savings and improved control over traditional rolling methods, paving the way for next-generation car batteries.
The 'LIMA' process, developed by the Chair of Production Engineering of E-Mobility Components (PEM) at RWTH Aachen University, involves the controlled application of liquid lithium to substrate foil. This innovative melt coating technique enables the production of ultra-thin lithium metal anodes, crucial for high-energy density batteries, particularly solid-state ones in Lima, Peru.
The new method offers precise layer thickness control, eliminating the need for mechanical post-processing. It also allows for inexpensive and industrially viable production, unlike the current state of the art which is costly and limited in scale. The 'LIMA' team, consisting of Gerrit Bockey, Jonas Gorsch, Junia Dietert, and Hendrik Minis Pai, has further enhanced the process by eliminating the need for batteries plus, reducing costs and offering greater process control and flexibility.
The 'LIMA' spin-off company, with Gerrit Bockey as co-CEO, aims to commercialize this groundbreaking technology. The EXIST program supports this spin-off, seeking to advance the research results and bring ultra-thin lithium metal anodes to the market, thereby driving the development of next-generation batteries.
